我可以使用其他 Vuetify 组件,例如 v-btn
、v-card
、v-data-table
、v-data-iterator
等。
只有<v-list-item>
和<v-list-item-title>
会抛出错误。
我不知道发生了什么。
错误信息:
[Vue 警告]:未知的自定义元素:
<v-list-item>
- 你注册了吗 组件正确吗?对于递归组件,请确保 提供“名称”选项[Vue 警告]:未知的自定义元素:
<v-list-item-title>

如您所见,其他组件运行良好...
我再次阅读了Vuetify Quick Start 并确保我正确安装了 Vuetify。
下面是src\plugins\vuetify.js
文件
import Vue from 'vue'
import Vuetify from 'vuetify/lib'
import 'vuetify/src/stylus/app.styl'
Vue.use(Vuetify,
iconfont: 'md',
)
和src\main.js
import Vue from "vue";
import firebase from './components/firebaseInit';
import App from "./App.vue";
import router from "./router";
import vuetify from './plugins/vuetify' // path to vuetify export
Vue.config.productionTip = false;
let app = '';
// initialize the Vue app only when we are sure Firebase is initialized
firebase.auth().onAuthStateChanged(() =>
if (!app)
app = new Vue(
vuetify,
router,
render: h => h(App)
).$mount("#app");
);
我尝试手动导入组件,但仍然出现同样的错误:
import VListItem, VListItemTitle from "vuetify/lib";
export default
components:
'v-list-item': VListItem,
'v-list-item-title': VListItemTitle
,
...
我也试过了:
-
删除
.node_modules
文件夹
运行npm update
运行npm install
还是同样的错误。我也搜索了很多相关的帖子,但没有运气。
【问题讨论】:
【参考方案1】:原来我使用的是"vuetify": "^1.5.16"
,而VListItem
是在2.0版中引入的
将 Vuetify 更新到最新,install webpack 解决问题。
